Summary
The reciprocity principle of Born, when used in the context of the phase-space representation of relativistic quantum mechanics, suggests a Yukawa-like equation whose eigenfunctions properly describe the baryon mass spectrum. Good numerical agreement with experimental data is established by introducing internal SU 3 symmetry, which when broken leads to a satisfactory quantitative description of the well-known linear baryon Regge trajectories.
Riassunto
Il principio di reciprocità di Born, quando è usato nel contesto della rappresentazione dello spazio delle fasi della meccanica quantistica relativistica, suggerisce un'equazione del tipo di Yukawa le cui autofunzioni descrivono propriamente lo spettro di massa barionico. Si ottiene un buon accordo numerico con i dati sperimentali introducende una simmetria interna SU 3, che quando è spezzata porta ad una soddisfacente descrizione quantitativa delle note traiettorie lineari di Regge del barione.
Резюме
Принцип взаимности Борна, который используется в контексте с представлением фазового пространства релятивистской квантовой механики, приводит к уравнению типа Укавы, собственные функции которого описывают массовый спектр барионов. Получается хорощее численное согласие с экспериментальными данными при введении внутренней SU 3 симметрии, нарущение которой приводит к удовлетворительному количественному описанию хорощо известных линейных барионных траекторий Редже.
